The Edge Geom Tool is an interface to those routines in the Tina system for performing
edge detection and subsequent pre-processing for stereo and the recovery of 2D
scene descriptions (There are significant changes between this tool and the largely
equivalent Edge Tool which was in version 4.0).

Two processing modes are available, "mono" and
"stereo" ; these relate to the mono and stereo management tools discussed in
section 2 of the user guide .

Menus for controlling the Pick and Mouse facilities of associated Tv devices are
provided. In addition "pop up" dialog boxes allow various default parameter
settings to be manipulated.

Edge data and the 2D geometry recovered from it is now always displayed and
manipulated (using the mouse) in real image coordinates even when the edges
themselves have been rectified into the equivalent camera coordinate frame
(recovered using calibration data).
